Let’s take an inventor, Thomas, who has come up with an idea for a new type of light bulb – one that is more efficient, longer-lasting and brighter than the rest. He has done so to serve his own self-interest, in the hope of making himself rich, and perhaps famous. The by-product will be to benefit society as a whole, by creating jobs for those who will make the bulbs and enhancing the lives (and living rooms) of those who buy them. If there had been no demand for the light bulb, no one would have paid Thomas for it, and the invisible hand would have, in effect, slapped him down for making such a mistake.
Similarly, once Thomas is in business, others may see him making money and attempt to outdo him by devising similar light bulbs that are brighter and better. They too start getting rich. However, the invisible hand never sleeps. Thomas starts undercutting his competitors so as to ensure he keeps selling the most. Delighted customers benefit from even cheaper light bulbs.

IMO, it would be unlikely that Thomas would have what it takes to come up with such an invention with greed as the motivation.
More likely that a large company would try to buy and suppress his idea or take the majority of profits for themselves. That's why we
need such entities as the ACCC...to keep a handle on the greedy at heart.
